* Mid-term hard milestones

1. Logic to extract debug symbols by explicit request in a pkgsrc
package.  For example, a package might look like:

DEBUGDATA_FILES+=	bin/fnord
DEBUGDATA_FILES+=	lib/libfnord.so.1
.include "../../mk/bsd.debugdata.mk"

Then pkgsrc will split debug data out of ${PREFIX}/bin/fnord into
${PREFIX}/libdata/debug/bin/fnord.debug.  (Note this need not cope
with, e.g., libtool shared libraries, libfnord.la -- OK if it is
rudimentary!)  OK to require changing the package's main plist for now.

2. User-settable mk.conf knobs for enabling debug data splitting, say
PKG_DEBUGDATA=yes, and for controlling the granularity of the debug
data (-g vs -g3 &c.), say PKG_DEBUGLEVEL= small/default/detailed, for
any packages that have debug data enabled.

* Mid-term would-be-nice milestones

3. Automatic searches, like check-interpreter, for

   (a) candidate files to extract debug data from, to make it easier to
   find ELF files with embedded debug data that might the developer
   might have missed, and/or check whether anything changed in updates
   since the DEBUGDATA_FILES were last recorded; and

   (b) binaries that have already been stripped, to help find mistakes
   with INSTALL_UNSTRIPPED early, before you're trying to debug a
   program whose debug data package is useless.

4. Fix for debug data pathname issue.

* Candidate final milestones [to be reviewed after midterm]

5. pkgsrc/mk support for simple multi-packages -- no conditional
dependencies or anything like that, just one binary package has one
plist and another binary package has another plist.  Something like:

PKGNAME=	foo
SUBPKGNAMES+=	foo-debug

# PLIST
bin/foo
include/foo.h
lib/libfoo.la

# PLIST.foo-debug
libdata/debug/bin/foo.debug
libdata/debug/lib/libfoo.so.1.debug

Then `make package' will produce foo-1.23.tgz and foo-debug-1.23.tgz.

6. Integration/polish:

   (a) handle libtool libraries appropriately,
   (b) automatically produce debug plists from DEBUGDATA_FILES,
   (c) convert various packages to use debug data,
   (d) perhaps automate the conversion

* Final would-be-nice milestone

7. pbulk support for multi-packages.
